Detecting TalkBack on a device

hi,
For an app i need to check whether TalkBack is active or not on the device and issue a message. How can this be done without plugins and just using Android Helper classes in unity.

From a stack overflow thread i got the native code for this :

Code (JavaScript):

1. AccessibilityManager am = (AccessibilityManager) getSystemService(ACCESSIBILITY_SERVICE);
2. boolean isAccessibilityEnabled = am.isEnabled();
3. boolean isExploreByTouchEnabled = am.isTouchExplorationEnabled();

How can we access this using android helper functions..

thanks in advance...

 

hi,
I was able to figure it out myself. Here is the code:

Code (CSharp):

1. using (var unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {
2.             using (var activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity")) {
3.                 using (var context = activity.Call<AndroidJavaObject>("getApplicationContext")) {
4.                     using (AndroidJavaObject accManager = context.Call<AndroidJavaObject>("getSystemService",new object[]{context.GetStatic<string>("ACCESSIBILITY_SERVICE")})) {
5.                    
6.                         return accManager.Call<bool>("isEnabled");
7.                     }
8.                 }
9.             }
10.         }
